Former All Black coach John Mitchell is to face a disciplinary hearing by South African Super rugby franchise the Lions.
Rugbyweek.com reports that at least 20 players have listed formal grievances against Mitchell.
Players are said to have been unhappy with Mitchell for some time but last week put their complaints in writing as verbal complaints were not yielding results.
An emergency board meeting last Thursday agreed that Mitchell be suspended.
The complaints are said to be about his lack of professionalism, and his continual swearing and belittling of players in front of their peers.
